Just a quick fan question 3wires=tach output?

[thebestMAX]

Do all 3 wire fans have a tack out for fan speed.

Just got a Vantec Aeroflow 7040 with the YS Tech TMD fan and it has 3 wires.

Somewhere I read on the forum it DIDNT have speed monitoring.

Anybody know?

Thanks

Edit: At what power drain do you have to worry about the fan burning out the headers on the MB like some Deltas?

usually the yellow wire is the rpm one.

Ok, im an idiot!

Found the fans spec and it says it has speed out. Wonder what those guys were talking about?

they were probably high at the time.

Yeah, it was in the reviews at NewEgg I saw it. Maybe Intel Users.
